(a) If you must pay an income-related monthly adjustment amount, your total Medicare Part B premium will be the sum of:

(1) The Medicare Part B standard monthly premium, determined using the rules in 42 CFR 408.20; plus

(2) Any applicable increase in the Medicare Part B standard monthly premium as described in 42 CFR 408.22; plus

(3) Your income-related monthly adjustment amount.
